I've been reloading a Winchester 270 with 117 grain hammer hunters, using Hornaday brass. I'm full length sizing and using a mandrel to size the necks, and found a great load using 58 grains of R16, .030 off jam....pretty much one jagged hole. With components so scarce, and with dreams of superhuman consistency, I purchased an AMP Annealer. Well, my perfect groups spread out like an egg hitting the floor. Not terrible, but from excellent to say 1 1/4 moa. Should I restart working the load back up to see if the nodes changed....or just mess a bit with the seating depth a bit. Anyone else experience this when they started annealing? I'd hate to re-work the loads on all my rifles...not pretty.
